Nanostructured Shape Memory Alloys: Adaptive Composite Materials and Components

Abstract

Methods for fabricating adaptive composite materials and components using shape memory alloy (SMA) constituents were investigated using a variety of fabrication techniques, including mechanical rolling methods. Both SMA-polymer and SMA-metal composites were created, as well as new fabrication strategies for producing NiTi and CuAlNi shape memory alloy particles with refined size which still display shape memory and pseudoelasticity. The composite materials show promising fracture toughness behavior. The functionalization strategy we developed for improving adhesion between a shape memory alloy constituents in a polymeric matrix provides tunable control over the interface. Additionally, related work on the manipulation and control of the motion of individual liberated nanowires using nickel end caps and magnetic fields has allowed us to achieve sample positioning for characterization and optical switching behavior.
